In a conventional dereverberation system, when there is a fluctuating reverberation component, it has been difficult to determine, with high accuracy, a linear dereverberation filter for removing a non-fluctuating reverberation component. An algorithm integrating a dereverberation system using a linear filter and a dereverberation system using a non-linear filter includes the function of measuring the amount of fluctuation in transfer function in a latter-stage non-linear filter over time, and controls the strength of the non-linear filter over time based on the function. In this configuration, a strong non-linear process is implemented only when the fluctuation in transfer function is large, whereby distortion in speech components can be minimized. Further, by feeding the amount of fluctuation in transfer function over time by the function back to the estimation of a previous-stage linear filter, and thus reducing the weight for a time band in which the transfer function of a linear filter estimated value fluctuates, the influence causing a decrease in estimation accuracy of the transfer function can be reduced.

Monitoring accuracy degrades due to a noise where many sound sources exist other than those to be monitored. A sound monitoring system includes a microphone array having multiple microphones and a location-based abnormal sound monitoring section. The location-based abnormal sound monitoring section is supplied with an input signal from the microphone array via a waveform acquisition section and a network. Using the input signal, the location-based abnormal sound monitoring section detects a temporal change in a sound source direction histogram. Based on a detected change result, the location-based abnormal sound monitoring section checks for abnormality in a sound field and outputs a monitoring result. The processing section searches for a microphone array near the sound source to be monitored. The processing section selects a sound field monitoring function for the sound source to be monitored based on various data concerning a microphone belonging to the searched microphone array.

The sound acquisition apparatus broadcasts a sound 'output notice request' through a communication network. In response to the request by the sound acquisition apparatus, the sound output apparatus gives notification of starting a sound output operation, the sound acquisition apparatus requests the sound output apparatus to transfer 'output sound data'. The sound output apparatus then transfers &#x201c;output sound data&#x201d; representing the sound outputted by its own speaker to the sound acquisition apparatus in response to this request. The sound acquisition apparatus then suppresses a noise component from sound data acquired through a microphone using the transferred &#x201c;output sound data&#x201d;.
